Solution
The correct option is
A
−
P
V
Since the process
C
to
A
and
B
to
D
are isochoric(constant volume), the work done in each process is zero.
Now, since the process
A
to
B
and
D
to
C
is isobaric, the work done will be,
W
=
P
i
(
V
f
−
V
i
)
Where
P
i
is the isobaric pressure and
V
i
and
V
f
are the initial and final volume of the gas respectively
Therefore,
W
A
B
=
2
P
(
2
V
−
V
)
=
2
P
V
And,
W
D
C
=
P
(
V
−
2
V
)
=
−
P
V
Hence the net-work done by the gas in the cycle is
W
A
B
+
W
D
C
=
P
V
And the net-work done on the gas in the cycle is
−
P
V
